Subgenus

In biology, a subgenus (plural: subgenera) is a taxonomic rank directly below genus.In the International Code of Nomenclature for algae, fungi, and plants (ICNafp), the subgenus is one of the possible subdivisions of a genus.There is no limit to the number of divisions that are permitted within a genus by adding the prefix "sub-" or in other ways as long as no confusion can result.[2] The ICNafp requires an explicit "connecting term" to indicate the rank of the division within the genus.In zoological nomenclature, when a genus is split into subgenera, the originally described population is retained as the "nominotypical subgenus" or "nominate subgenus", which repeats the same name as the genus.
